There are tons. Open models + open source harness are already on par as a product and very likely to be a seamless substitute for most users.

On par? Hardly.

Moreover peruse any ai dev forums and you’ll see preferences towards one or the other (Claude/ChatGPT) due to capabilities.

So long as theres a felt gap between open models and frontier you will have people pay for the best of the best. Not doing so is an admission of actively handicapping yourself and not in a way that is easy to justify.

There are other reasons why people are using Claude/ChatGPT.

When the company is big enough, the decision doesn't rest on developers and execs are much more likely to go with established vendors -> no open models

When the company is small enough, the 200$ plans from either ant or openai are way way better value for money than anything you can get with open models. This may change in the post-IPO future.

It is as simple as that.

Have you tested this yourself? Open models are absolutely not on par.

I do hope they eventually will be on pary but right now they are far behind

[delayed]

Every time DeepSeek come out with a new model, I am always impressed, especially with the extremely low cost compared to Claude's metered costs.
